PATENT OFFICE HARRY C. HAYES, OF DETROIT, MICHIGAN, ASSIGNOR TO GENERALNECESSITIES COR- PORATIQN, OF DETROIT, MICHIGAN, A CORPORATION OFMICHIGAN CONDENSER Application filed May 4, 1927, Serial No. 188,832.Renewed August 1931.

liquid below that necessary to convert the re frigerant from gas toliquid.

Referring to the drawings:

Figure 1 is a front elevation of the condenser and cooling apparatuspartially in section;

Figure 2 is a plan view thereof;

Figure 3 is an end elevation thereof.

Referring to the drawings in detail, 1 in dicates a pipe for conveyingthe incoming refrigerant gas, such pipe being continued in a pluralityof successive loops. Interior-1y of 'the successive loops of the gas ppe -1 are passed similar successive loops of a water vpipe 2. Atthebottom of this series of loops 2 of the water pipe and the gas pipe islocated a tilted reservoir 3 for refrigerant liquid with which the openend 4 of the gas pipe 1 communicates so that the gas which has been'condensed to a liquid in the gas pipe. 1 will empty into the liquidreservoir 3.

The water pipe 2- makes its exlt through the open mouth 4 of the gaspipe 1 entering the reservoir-3 where it'is formed into a plurality ofcoils 5 resting on the bottom of the reservoir and being immersed in therefrigerant liquid. The water pipe'makes its exit through the linedesignated 6. The water enters through the pipe 6 in the direction ofthe arrow traveling in a reverse direction 0 to that of the refrigerant.The refrigerant liquid which is cooled by the coils of the water pipe 5below the temperature necessary for the condensation oft-he gas of therefrigerant makes its exit through the exit line 7. The coils of pipes 1and 2 are supported by plying the coldest water to the condensedretheusual brackets 8 which may be of any de of condensation, utilizingthe same current of water through the same pipe system first apfrigerantand then the water is applied to the gas where the temperatureneed notbe as low as that utilized in reducing the refrigerant-liquid to a lowertemperature in loirder1 to reduce the gases to a condensed u1 It will beunderstood that I desire to comprehend within my invention suchmodifications as may be necessary to adapt it to varying conditions anduses.

Having thus fully described my invention, what l claim as new and desireto secure by Letters Patent, is:

1. In combination, a refrigerant coil for use as a condenser, areservoir connected therewith for collecting the condensed refrigerantfrom said coil, and a cooling fluid pipe passing intoand located withinsaid reservoir and thence passing through the interior of therefrigerant gas coil.

2. In combination 'a refrigerant gas pipe coiledrfor useas a condenser,a cooling water pipe insaidcoiled gas pipe, and a reservoir connected tosaid'refrigerant gas pipe for collecting condensed refrigerant, saidcooling water pipe passing through the reservoir and coiled therein.

3. In combination, a refrigerant gas pipe coiled for use asa condenser,a cooling water pipe passing through said coiled gas pipe, and areservoir connected to said refrigerant gas pipefor collecting condensedrefrigerant, said cooling water ipe passing through the reservoir andcoiled therein, said water pipe -inthe reservoir and the water pipeassociated with the gas coil being 90 formed of an integral pipe wherebythe incoming cold water to the coil will reduce the temperature of therefrigerant in the reservoir first and then reduce the temperature ofthe gas in the condenser coil on the way to the water exit.

4. In a refrigerating apparatus, a reservoir', a vapor pipe coiled abovesaid reservoir with one end inserted in said reservoir, and

a cooling pipe extending through the reser voir and through said vaporpipe, said cooling pipe being coiled in the reservoir.

In testimony whereof, I afiix my signature.
